More Stars Will 'Stand Up To Cancer' On Telethon

The list of major film and television stars who have signed on to participate in the third Stand Up To Cancer telethon has grown to include the likes of Tom Hanks, Justin Timberlake, Halle Berry, and a pair of Olympic gold medalists in addition to previously announced names such as Matt Damon, Julia Roberts, Michael Douglas, and executive producer Gwyneth Paltrow.

A unique feature of the telethon is that celebrities will man the phone bank and talk to donors when they call in with their pledges. Also on tap will be musical performances from Coldplay, Alicia Keys, Tim McGraw, and Taylor Swift. Patients involved with Stand Up To Cancer medical trials will be on hand to share their experiences with viewers as they are encouraged to call in and donate money to the cause.

Since the telethon was established in 2008, the organization has raised more than $180 million for cancer research and awarded grants to seven different multidisciplinary research teams of scientists searching for innovative ways to combat the deadly disease. Spider-Man movie producer Laura Ziskin founded Stand Up To Cancer and produced the first two telethons in 2008 and 2010 before tragically losing her seven-year battle with breast cancer last year.

The hour-long television special will air without commercial interruptions on Friday at 8:00pm Eastern on ABC, CBS, FOX, NBC, and over a dozen cable channels including TBS, HBO, HBO Latino, Showtime, Starz, MLB Network, BIO, Encore, ION Television, LMN, Logo, mun2, Palladia, and Smithsonian. The following is the full list of celebrities scheduled to appear thus far:
